Nutritional cost reduction and increase profitability in commercial broiler production using phytase superdosing

ABSTRACT The objective of the present study was to evaluate the reduction of calcium (Ca), crude protein (CP), metabolizable energy (ME), and available phosphorus (aP) in the nutritional matrix of Brazilian commercial broiler diets supplemented with both phytase superdosing (1500 FTU/kg) or conventional doses (500 FTU/kg) on the feed cost and profitability, performance, bone mineralization, and carcass yield of broiler from 1 to 42 d. A total 1200 one-day-old chicks (Cobb 500) were randomly distributed in a commercial feeding program [...]
